  • High-efficiency models save water, reducing utility bills.
  • Durable construction ensures longevity.
  • Variety of designs to fit different bathroom styles.
  • Some models feature innovative flushing systems for better cleanliness.
  • Easy to clean surfaces.


  • Higher-end models can be expensive.
  • Limited color options compared to some other brands.

The only complaint that American Standard users have had about their flushing systems is the sticking of substances at the back of the toilet. Some American Standard flushing systems are not sufficient and leave waste marks after flushing. So, you may have to clean your toilet more often than expected.

Ease of cleaning

This depends on whether the toilet is a two-piece or one-piece unit. Generally, one-piece toilets are simple to clean than two-piece toilets. If you want a toilet that won’t give you a headache to clean, then consider going for a one-piece unit. Such toilets don’t have a gap between the tank and bowl where mold, mildew, and bacteria grow from.

When it comes to these two brands, you can say that American Standard toilets are easier to clean as most of them feature an EverClean surface, while Kohler doesn’t. The EverClean surface keeps the toilets clean for longer by preventing the sticking of stains and waste on the bowl.

However, even without a special coating, most Kohler toilets don’t allow substances to stick to the bowl. And that’s why you don’t hear people complaining about Kohler toilets being hard to keep clean. Actually, Kohler toilets are easier to keep clean as the AquaPiston flushing system pushes everything down the drain. This is not the same case with the class five flushing system, which tends to leave waste marks at the back of the toilet.

Ease of installation

You will never have an issue installing any of the toilets. Of course, unless it is a one-piece toilet with a skirted bowl. These tend to be more challenging to install than ordinary toilets. Also, one-piece toilets are slightly heavier and thus more challenging to install than two-piece units.


If comfort is what you’re looking for, then you can never go wrong with Kohler toilets. The brand offers the best-elongated bowl toilets on the market. Also, most of their toilets are of chair height, which means that they can accommodate different users without any issues. This doesn’t mean that American Standard toilets are not comfortable, but when compared to Kohler toilets, it has the edge over them.

  1. My 2 year old toilet wasn’t flushing well, and normally not at all. I frustrated all the regular recommendations. Nothing worked so I called the plumber. He checked it out and said I most probably needed a new toilet. And I hope, this toilet would be help me. Thank you for your share
